Multiple modes of speciation involved in the parallel evolution of sympatric morphotypes of lake whitefish (coregonus clupeaformis, salmonidae).
TL;DR: The authors performed a phylogenetic analysis of mtDNA variation among seven sympatric pairs of dwarf and normal morphotypes of whitefish from northern Quebec and the St. John River drainage to address three questions relevant to understanding their radiation.

Experimental Invasions Using Biological Control Introductions: The Influence of Release Size on the Chance of Population Establishment
TL;DR: The implication from these results is that the demographic factors whose influence depends on population size or density such as demographic stochasticity, Allee effects, and genetics play important roles in the establishment of invading populations.
Journal ArticleDOI
Models of evolution of reproductive isolation
TL;DR: Computer simulations by using Itô's stochastic differential equations have shown that in the model used the reproductive isolation mechanism evolves faster in small populations than in large populations when the mutation rate remains the same.

TL;DR: A combination of introgressive hybridization and selection jointly provide the best explanation of convergence in morphology and genetic constitution under the changed ecological conditions following a major El Niño event in 1983.
